ISAAC WOOD, OF MINNEAPOLIS, MINNESOTA,

OIL-GAS BURNER.

SPECIFICATION forming part of Letters Patent No. 513,028, dated January16, 1894. Application filed August 26. I893. Serial No. 484,112. (Nomodel.)

To alt whom it may concern:

Belt known that I, ISAAC WOOD, of the city ofiMlnneapolis, county ofHennepin, State of Minnesota, have invented. certain new and usefulImprovements in Oil-Gas Burners, of which the following is aspecification.

My invention relates to means for generating gas or fine oil vapor fromoil, and mixing the same with air immediately before ignit on; and theobject of my invention is to provide a cheap, compact burner which willaccomplish the above results and which will in itself, permit of an easyadjustment to secure the best work under varying conditions.

A further object is to so construct a burner that repairs thereon may beeasilyand cheaply made; and further, one which may be cleaned and lieptin good order by any person.

Wlth the above in view, my invention conslsts 1n certain constructionsand in combinations all as hereinafter described and partlcularlypointed out in the claims.

The invention will be more readily understood by reference to theaccompanying drawlngs, in which- Figure 1 is a plan view of a burnerembodying my invention, portions being broken away to more clearly showunderlying parts. Fig. 2 is a vertical section on the line ocw of Fig. 1Fig. 3 is a perspective detail, partly in sect1on,showingmodified formof discharge head.

As a base for the burner, I provide the plate 2 which is-made to fit thefire box and prevent the upward draft of air, except through a speclalinlet hole 3 of the plate for each burner employed thereon. Above thishole or aperture 3 is a cap-ring or housing 4,0pen at the top butnormally closed and completed by a lid 5 setting down over a rim on thering and actlng to prevent a direct upward draft compelling the air topass through the hereinafter described mixing chambers. The openingwithin the ring is of about the size of that in the plate. The heatretaining ring or cap is supported upon a number of boxes 6, sectorlikein form and having the upwardly and outwardly inclined bottoms 7, whichterminate in the curved or upwardly flaring lips 7 acting as deflectorsto throw the flames upward. The mixing chambers or boxes 6 areadjustable in all directions and are locked by through the end 12 and isheated and vaporized in the coil, being then discharged into the head13, from whence it is emitted through the comparatively small openings14 arranged either in the walls of the hollow head 13 or in smallnipples 15 extending therefrom. These openings through which the oil gasis discharged are located in front of the mixing chambers and the gasjets play across and create upward flowing currents of air through thebottom, which air being intensely heated, mixes thoroughly with the oilgas and is ignited in the long narrow mouths formed between the lips 7of the boxes and the ring 4..

When the burner is in use the openings under the ring and between theboxes are filled with a suitable composition to prevent the entrance ofconflicting drafts.

It often occurs that a slight variation of the position of a box ormixing chamber will cause the burner to work better, and such adjustmentis made easy by the use of independent boxes or mixing chambers with thelocking means described. When the cap is taken ofi, a bent needle may beeasily inserted to clean out the jet holes, the same being countersunk,as shown, to guide the needle to the center.

While but three boxes are shown in the drawings, it is obvious that anynumber may be employed.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. The combination, in an oil gas burner, of a plate,with adjustable mixing chambers or boxes thereon, a cap arranged abovesaid boxes, which latter have discharge openings, and means forinjecting oil gas or vapor into said boxes and for admitting air withthe gas, substantially as described.

2. The combination, in an oil gas burner, of a plate or base, withmovable mixing chamhere or boxes, means for locking said boxes onsaidplate, said plate having a central opening to lead air into saidchambers, and means for injecting oil gas or vapor into the inner endsof said chamber substantially as described.

3. The combination, in an oil gas burner,

of a base plate, having a central air opening, 1

with mixing chambers or boxes movably arranged about said opening, aheat retaining ring or cap arranged above said boxes, means for lockingsaid boxes in place, a super-heating coil arrangedabove the boxesbeneath said cap, and a central discharge head 'for said coil said headhaving jet openings oppo site the several mixing chambers or boxes,substantially as described.

4. The combination, in an oil gas burner, of a base plate having acentralopeningwith sector shaped mixing boxes or chambersarranged aboutsaid opening, and having the 20 ISAAC WOOD.
